DRAIN-PXPE POCKET.

Speciicatiou of Letters Patent. Patented Spt., LS, ltllil Tf.,

lApplication led September 1, 1915. Serial No. c18,1195.

To all whom 'it may concern.'

Be it known that I, THOMAS J. MCKEONE, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful lmprovements in Draindf'ipe Pockets, of which the' following` is a specication.

The invention relates to pockets for drain lo or waste pipes and the like and has for an object the provision of a pocket for collecting foreign matter passing through or into a drain, waste or other pipe, without necessarily restricting the flow of fluid through the pipe.

Among other features the invention co1nprehends a proportion of size between the pocket and the particular pipe into which the pocket is fitted so that the waste water or other fluid will not be dammed or materially obstructed in its How.

Stillfurther objects of the invention reside in a pocket of simple construction, which is preferably made integral and te which can be readily secured in the desired relation to the pipe for which it is intended.

In the further disclosure of the invention reference is to be had to the accompanying 3@ drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:-

Figure 1 is a fragmentary vertical secte tional view taken through a waste pipe and trap, showing my device applied, y Fig. 2 isa perspective view of the pocket, and y F ig. 3 is a horizontal sectional view taken a@ on` the line 3-3 in Fig. 1.

, Referring more particularly to the views disclose a Waste pipe 10 connecting with, a head 11 of a coupling pipe 12 associated with the usual trap 13, said coupling pipe conte stituting, in fact a continuation of the drain for Waste pipe l() and with which thc coui pling pipe is associated at the ground level 14.

i The pocket, indicated by the numeral 15,

5o, consists primarily of a cylindrical body 16, having a preferably curved bottoml? and provided with numerous perforatlons or openings 18, in the side and bottom. An annular flange 19 is formed with the upper open end of the body 16 and provides for 55 the dependence of the body in the coupling pipe 12 as shown in Fig. 1. To this end the head 1l is formed with a seat 20, receiving the iiangc 19 and as clearly set forth in Fig. 2, and also in Figs. 1 and 3, the flange tu 19 is formed with scallops 21, providing small openings 22.

1n practice the pocket is arranged as shown in Fig. l and it will be noted that the body 16 is entirely spaced from the wall of t5 the coupling pipe into which it depends, `the said body being dependingly supported by the flange 19. Now it will be clear that foreign matter passing into the pipe l2 with the fluid from the drain pipe 10, will be 270 caught in and lodge in the pocket, the openings 18 being too small to permit of the passage of the foreign matter out of the pocket with the fluid. -The openings 22 are also too small for the foreign matter to pass 7&3 through but permit small quantities of waste water or fluid, flowing down the side of the drain pipe, to readily flow unhindered into the coupling pipe.

As mentioned heretoforethe pocket 15 is et made proportional to the size of the coupling pipe, so that when a pipe of a certain diameter and length is ordinarily used. when no pocket is employed, the pipes in the present instance will be of increased size to accommodate the dow of water or fluid. With this feature of the construction the damming of the waste water will be prevented, While the pocket, disposed in the pipe l2, as shown and described, will pre- Vent obstaces or other foreign matter from passing into and clogging up the trap 13.

By having the pocket 15 associated with the pipe 12 at the ground level 14, it will be clear that the pocket can be easily and quickly removed for the purpose of clearing out the same, without necessitating the digging up of the gr( und, the breaking away of any cement or the removal of the trap and component parts.

In combination with a vertically arranged pipe having a diametrically enlarged head at the upper end, providing an annular seat, a

vertically arranged pocket in and of less diameter than said pipe, said pocket having a, perforated Wall and being provided at the l upper open end with an outwardly extending 5 annular flange which bears on said seat and suspends' and supports the pocket, Said ange having a scalloped outer edge lpro- Viding openin s between the seat and the Wall of the poc et and permitting the pocket to be readily lifted. 10V
